Preamble puncturing configuration information is encoded in a pad field, and alternatively or additionally, in a Service Field, depending on a transmission bandwidth of a Physical Layer Convergence Protocol (PLCP) Protocol Data Unit (PPDU). Some implementations also encode one or more parity bits in the pad field or Service field. The PPDU including the preamble puncturing configuration information encodes, in various embodiments, a request to send frame, a clear to send frame, a power save poll frame, or a contention free end frame.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, further comprising encoding the preamble puncturing configuration information via both the pad field and the first value of the first Service Field.
4. The method of claim 1, wherein the transmitting of the non-HT PPDU transmits the non-HT PPDU over an 80 MHz bandwidth, and the 80 MHz bandwidth comprises four 20 MHz sub-channels, and wherein the preamble puncturing configuration information indicates one of no preamble puncturing, a first channel of the four 20 MHz sub-channels is punctured, a second channel of the four 20 MHz sub-channels is punctured, a third channel of the four 20 MHz sub-channels is punctured, or a fourth channel of the four 20 MHz sub-channels is punctured.
5. The method of claim 1, further comprising encoding an indication of the preamble puncturing configuration information within three bits of the pad field.
6. The method of claim 5, further comprising determining the first parity value as a parity bit based on the three bits.
7. The method of claim 6, wherein the parity bit is an even parity bit.
8. The method of claim 1, wherein the transmitting of the non-HT PPDU transmits the non-HT PPDU over a 160 MHz bandwidth, and the 160 MHz bandwidth comprises eight 20 MHz sub-channels, and wherein the preamble puncturing configuration information indicates one of no preamble puncturing, an indication identifying a contiguous pair of sub-channels that is punctured, or an indication identifying one of the eight 20 MHz sub-channels that is punctured.
9. The method of claim 8, further comprising encoding an indication of the preamble puncturing configuration information within four bits of the pad field.
14. The apparatus of claim 13, the operations further comprising encoding the preamble puncturing configuration information via both the pad field and the first value of the first Service Field.
19. The non-transitory computer readable storage medium of claim 18, the operations further comprising encoding the preamble puncturing configuration information via both the pad field and the first value of the first Service Field.
